TI Introduces Crystal-less MCU Using BAW

The crystal oscillator is a longstanding concept that employs a physical oscillator for clocking to facilitate accurate timing in electronics. These oscillators have been driving CPU clocks, as well as low frequency (and low power) non-CPU clocks in devices that need to be able to use their peripherals (for example: analog to digital converters) while…
